To all whom it "my concec'n:

Be it known that l, BENJAMIN l LAKE, a citizen out the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Vehicle-Tire, of which the following is a specification.

My invention relates to a vehicle tire structure and more particularly to a spring tire for automobiles and other vehicles-and has for an object to provide a tire which is not only puncture proof but which embodies the resiliency necessary to carry out the function of a device of this character.

It consists of a tire formed of a plurality of convolutions of suitable material to give the desired flexibility and resiliency and which oonvolutions are provided with seats tor a suitable tread member, With removable means embracing a suitable portion of said convolutions and clamping means engaging said removable means for holding the tire in position.

It further consists oil a novel structure of a. tread member formed of suitable resilient material which is adapted to be'situated in the seat or receiving means formed in the convolutions, said tread member being pro vided with means for preventing creeping or movement thereof.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention I have shown, in the accompanying drawings, structures embodying the prin ciple of my invention and which Will operate successfully in practice, giving satisfactory and reliable results, but l. desire it understood that the arrangement of the parts may be varied, other instrulnentalities may be employed and changes made in the oonstruction and I do not therefore desire to be limited to the arrangement as herein shown and described but desire to make such changes as may come Within the scope of my invention.

Similar numerals of reference indicat' corresponding parts in the figi Referring to the drawin one section of my novel tu- "no: same comprising a convolution of? other suitable material, the one... pass each other and extendon ccch downwardly, preicrobly on a curve, l

the same radius the n'uiin portion of the convolution and terminating at a point ad" jacentthe rim engaging sufl'lh -e "o 3 of the convolution. At a s1: ble poi: 1.: each side out the convolution as at l, the ma terial is depressed being clnrved or lent doivnwardly, forming a seat or socli'ct in r. c of, said seat or recess being adapted re ceive a suitably formed tread Member ll, of any suitable material, in the present instance the same being shown as for led of rubber, substantially solid and thus puncture proof, although any suitable form of tread may be employed. As stated, the end portions of the convolution terminate adjacent the rim engaging portion 3 of the cmivolution so that as will be noticed more particularly from Figs. 2 and 3, each convolution has two laterally disposed portions of the material at the points it and at the seat. or socket formed in these convolutions, while a single portion oi the material only, forms or serves as the rim engaging surface of a convolueach convolution at the outer portion th r ,tion. 1: preferably desire to taper the end portions 2, beginning at a suitable point and I also taper or flatten the exterior sidesof the depressed portions of the material which forms the seats or sockets. in order that the planes of the edges of each convolution will be oppositely inclined to a radial plane. as ,Will be apparent from. Fig. 3., A further function of the ends of each convolution is to form a stop or limiting means to prevent movement ot a sect ion by cn aging With the removable engaging means, in the present instance shown as a clip 7 which is preferably formed of suitable material and is adapted to embrace the single or rim engaging portion 01 the convolution between the ends 2. lhis clip 7 prefervbly' provides a body portion substantially tJ-shaped in order to suitably embrace the said rim engagincportion of the con volltion and each clip, being provided, protein with, with ears 7* projectiu. outwardly from each side 0" a-convolution and which serve l menus with which a; uita t ic integral therei clamp member cooperates to secure the clip and the convolution, and so the tire section,

I to a rim construction.

plete unitary tire structure when secured in place upon a suitable rim. It will be noted that the recess or seat provided by the con; volutions is of suitable extent in order that the portions 4 or" each convolution will extend a suitable distance above the center of the tread member 6, which latter will be of such size in order that it will be necessary toforce the same over one of the points after which the tread member will contatt, into position in the seat or socket formed in the sections and will firmly engage there with since the same is preferably smaller than the circumference of the seats. The inner surface of the tread member 6 is iret erably formed with corrugations or recesses 8, see Fig. 2, in order that each corrugation or recess will'be adapted to receive a suitable portion of the material forming the convolutions and it being noted that by these means some ofthe material of the cad will be positioned between adjacent portions of the material forming the seat or recess in a convolution to prevent creeping or movement of the tread 6. Any suitable means for securing the-convolutions in position may be employed and in the present construction I have shown the tire secured to the rim of a vehicle wheel by means of a plurality of sections 9 and 10 which are adapted to be suitably secured to the telly ll of the vehicle wheel. These rim sections in the present instance consist of annular rings passing circumferentially around the telly 11, one of which is provided with a tongue 12 while the opposite section is provided with a slot 13 adapted to receive said tongue, whereby when the two sections are in position upon the telly 11, these members provide an mterfitting connection between the sections which forms a substantial and strong means of preventing radial movement of the said sections. In the present instance I have shown a bolt 14, any suitable number of which may be employed around the telly 11 for securing the section 9, in the present instance, thereto and I have shown a rod 15 passing through the sections for locking the same together, it being noted that each section is provided with a suit-able lip 16 adapted to engage with extending ears on the convolutions to secure the same to the rim or the folly of the wheel.

It will be noted that the ends 2 are so formed and positioned in order to provide for the thicknesses of the clips in such a manner that when in place upon the rim or folly of the wheel, the planes of the edges of each convolution will be oppositely inclined to a radial plane in order that the convolutions will form a substantially continuous surface, as will be more particularly seen in Fig: 2.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a tire, a. plurality of convolutions of suitable material, each convolution being depressed at the outer portion thereof to form a seat, the ends of each convolution passing each other and extending toward the rim on each side of said seat, and a tread member held in said seat.

2. In a tire, a plurality of convolutions of suitable material, each convolution being depressed at the outer portion thereof to form a seat, the ends of a convolution passing each other, and extending on each side of the seat, the outer edges of said depressed portions and the said ends being tapered, and a tread member held in said seat.

A spring section for a tire consist ng of a coil having a tread supporting portion and a rim engaging portion and formed of a convolution of spring material depressed at the tread supporting portion toform a seat, the ends of the section extending upon opposite sides of the seat, whereby two portions of the material form the seat of the section.
